In order to evaluate the animal welfare and behavior of pregnant swine breeders in collective gestation systems, its consequences on the performance of the maternity and the effects on the behavior and welfare of the animals was developed in this study. Behavior assessments were carried out in a commercial farm, located in the municipality of Ipameri -GO during the months of May to July 2019. For this purpose, thirty pregnant sows of the same commercial lineage and with gestational period of 70-80 days and 100-110 days were observed. The sows were housed in a collective system in groups of 10 females per pens. During the observational period and in the morning and afternoon, behavior data were collected through photos, videos and ethograms, environmental data collected through a datalogger that stored information with an interval of 30 minutes and located inside the shed, in addition to thermographic images and respiratory frequency. Descriptive statistics were used for data analysis. It was observed that in the morning the sows remained more time feeding and moving, while in the afternoon the leisure behavior was predominant. There was also the effect of the gestational period on the behavior of the females, who at the end of gestation expressed a calmer behavior when compared to the period of 70 to 80 days, as well as the effect of the environmental and thermographic variables that demonstrated the effect of bioclimatology under the pregnant sows behaviors. Ambient temperature and gestational age interfere with the behavior of the sows housed in the collective management system.
